135920 divided by 23 
We want to figure out the number of times 135920 can be divided by 23.

On to step 1:
When dividing 1 by 23, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 23

Going ahead to step 2:
23 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 23

Moving on to step 3:
The number 23 fits into 135 5 times, leaving a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 115 from 135 leaves us with 20.
Fetch the next digit (9) from the dividend, attach it to 20 and continue: 209 / 23

Let's proceed to step 4:
209 divided by 23 is 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 59.0
Subtracting 207 from 209 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 23

Going ahead to step 5:
If we divide 22 by 23, we get 0 and a remainder of 22.
The number 0 becomes the next digit in our result. 
Result so far: 590.0
Subtracting 0 from 22 leaves us with 22.
Include the next digit (0) from the dividend after 22, then repeat: 220 / 23

Advancing to step 6:
When dividing 220 by 23, we get 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 5909.0
The remainder is 13 after subtracting 207 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
23 goes into 130 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 5909.5
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 8:
The number 23 fits into 150 6 times, leaving a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 5909.56
Subtracting 138 from 150 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
The number 23 fits into 120 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 5909.565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
The number 23 fits into 50 2 times, leaving a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 5909.5652
Subtracting 46 from 50 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
23 goes into 40 1 times with a remainder of 17.
The next digit of our result is 1. 
Result so far: 5909.56521
If we subtract 23 from 40, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 12:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 5909.565217
Subtracting 161 from 170 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 13:
90 divided by 23 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 5909.5652173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
23 goes into 210 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 5909.56521739
Deduct 207 from 210 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The final result is 5909.56521739 with a remainder of 3e-09.
